I went on Saturday night, after having a look in the afternoon. Atsadaeng road is blocked in front of the ministry, no boys there. Everywhere else business as usual, a bit weaker than usual. Nonetheless, I found one.
I was hoping for a concentration on one place (as pong indicated), but no, stretched out as usual. Driving around in a taxi is not my style, and walking it takes about 30 minutes for one round.
